Well, I feel that a persons range of intelligence is determined at his birth, but his upbringing and such can either bring him closer to the top of that range or nearer the bottom. Anything 100% mental requires people whose intellect exceeds that of others. If Bob is much much smarter than John, Bob's more likely to not only do well in Quantum Mechanics, but also to even comprehend it.
